we need to sum the two areas
First Area
Area of the rectangle is
[tex]A=b\times h[/tex][tex]\begin{gathered} \frac{2}{5}\times\frac{9}{10} \\ \\ \frac{18}{50}=\frac{9}{25} \end{gathered}[/tex]Second Area
[tex]A=b\times h[/tex][tex]\begin{gathered} \frac{3}{5}\times\frac{3}{5} \\ \\ =\frac{9}{25} \end{gathered}[/tex]Sum the areas
[tex]\begin{gathered} \frac{9}{25}+\frac{9}{25} \\ \\ \frac{9+9}{25}=\frac{18}{25} \end{gathered}[/tex]the total area is 18/25 square meter
